To allvwromz't may concewv.'

Be it knownthat 1DANIEL 'WL SMITH, a citizen of the United States,residing at Bangor, in the countyy of Penobscot` and State of Maine,have. invented Acertain new and useful Improvements in lVood-SawingMachines; and I do declare` the following` to be a', full, clear,- andexact :descriptionoi' the invention, such as will enable others skilledin the art to'which it appertains to make vand use the same.` f

My invention relates tov new improvements in wood-sawing machines of atype which .can be used by one manfor either felling trees` orfor-sawing logs intoV desired lengths. y

It is the object of the invention to provide a generally improved andsimplified construction whieh may be .easily set up and operated by oneman, and may be conveniently folded and carried from place to place. f h

lliththe foregoing in view, the invention Figures 4, 5 andG aretransverse sectional views as indicated by the correspondingly numberedlines of Fig. 8..

Figure 7 is a detail transverse section on line 7-7 of Fig. 1. f y

In the drawings above briefly described,

the numeral 1 designates a main, elongated supporting bar whose frontend portion 2 .is. preferably at a widely obtuse angle to itsV bodyportion.k The rear end of'tlie bar 1'. is providedwitlr a bearing 3having 'a clamping screw 4, which bearing adjustably receives asuitablyl constructed supporting leg 5 for use when felling trees only.Project ingl laterallyyfroml the front portiony of rthe bar 1 is-astationary jaw 6 .which is ,cof

operable with 'an opposed 'movable jaw 7. This movable jaw is providedwith a. fulcrum 8 engageable with'notches 9 in upper and lower metalplates 10 and l1 which eX- tend longitudinally of the front end 2 oftheaforesaid bar 1and said jaw 7 is provided and useful i with a rearwardlyextendingoperating lever g 'L5-sana# PATENT, ofFFi-ea. i]

V12,11avinga longitudinal flange laengagerable witlra suitable,rack 14which projectslaterally the bar 1. The, plate 11i-s,-v preferably insetin the upper side. of thel bar. 2 and isi secured to the latter by anypre--I ferredumeans such as vbelts 15, andthe` remote from the jaws 6.Vand 7 toothed or notched edge of thisplate,pro.-.. y `jects.. laterallyfrom the edge of .the bari, .1j

The upperplate 10. is carried entirely yby arigidlongitudinal; bar. v16,secured toitin any desiredY inanner',lthe inner or-:rear endv of, thisbar, being' bent. downwardly andsecuredat17f7 toy the main supportinglbar 1. It will? be observed. from Fig. 2, that the fi'fonten'ds.`

of theplatesl 10 and 11` are .absolutely free of connection with eachother 'andarespaced apart vertically.v This permits exception7 ally easyinsertion of thejaw 7 between these plates, andv alsopermitsltliexjawpto ybe re.-v

It istobe further noted,'tliat thegjaw 7 may -be adjusted teeny desireddistance'` with respect'to. tliej aw 6,.and its fulerum then engagedwith certain of the notches 9, where upontlie lever 18 may be actuatedto tightly move'thejjaw 7 intoi gripping relation withl 4 the jaw 6, themovablej aw being then held.-

by the flange 13 and rack 14E'.

a length. ot channel metal,l longitudinally split' at one end and havingtheV body po-rtion of such end bentlaterallyas at*19.(Fig-. l

1) aiidlbolted to one edge ofthe main supportingbar 1. f- The remainingportion ofthe channel bar, at theV split end of the lat-V ter, entendsacross the upper side of the l and the latter is transversely groovedfasLv at 20, adjacent said remaining portion, vthe latterA beingindicated at l2l. This construc-v tion is provided fora purpose to;appear,

but ity` may be statedizat thispoint, that, a

connection 22. is provided between the outer end ofthe track 18 and thestationary j aw- 6, so that'they relatively brace each other.

A saw-carrying arin 23 extends longitudinallyv ofthe mainysupportingbar1 `and' has its rear end pivoted4 at 24e to. the rear end of said bar.This arm 28 isprovided with a longitudinal track or runway 25 engaged bysuitable rollers 26 on a saw carriage 27, asaw 28 being secured to thiscar- Projecting laterally from thefban 1,-in rearwardly spaced relationwiththe station? ary jaw 6,;is-a curvedy track or arm 18, thisl arm ortrack being preferably formed from being mounted on an arm 33 whichprojects laterally from the rear portion of the main supporting bar 1.One end of this spring is connected at 34 with a swinging .arm 35 alsosupported by the arm 33, said swinging arm being in turn connected at 36with the saw-carrying arm 23. For tensioning the spring 32, a hand lever37 is connected to said spring, said lever being co-operable with acurved rack 38 carried by the bar 1. When* this lever is engaged withtheV rack after placing the spring 32 under tension, the latter will ofcourse act to swing the arm 23 and the saw 28 toward the tree or log,but when said lever is disengaged from the rack, the saw and the arm 23may be swung into close relation with the main supporting bar 1.Preferably, a handle 39is` provided on the arm 23 to effect thisswinging of the arm and saw.

To hold the arm 23 in a position contiguous to the bar 1, as shown inFig. 3, so that the device may readily be carried from one vplace toanother, I provide an appropriate latch 40 which is mounted on the bar 1and is engagea-ble with the arm 23, as shown most clearly in Figs. 3 and5. When this relation of parts exists, the saw V28 is preferablyengagedy with an appropriate hook 41, as shown in Figs. 1, 3 and 6, sothat said saw cannot yield or spring sidewise away from the front end 2of the bar 1.

For reciprocating the carriage 27, I provide a handle which preferablycomprises two telescopic sections 42 and 43 and a set screw 44 forrelatively securing them. One of these sections is pivoted at 45 to thecarriage 27, and the rear vend of the other section is provided with atransverse handgrip 46.` This form of handle permits the operator toyreadily actuate the machine while in a standing' position, even thoughsaid machine `may be located very close to the ground. When the machineis to be carried from one place to another, the handle is foldedforwardly and engaged with an appropriate hook 47 carried by the barl 1as shown in Figs. 3 and 5. Preferably, the bar 1 is provided with acarrying handle 48 by means of which the entire machine may be readilycarried in one hand, whenever necessary.

It will be seen from the foregoing that I have produced a greatlyimproved and simplified sawing machine, and one which will be easy tooperate, and very efficient. As excellent results have been obtainedfrom the general construct-ion disclosed, it is preferably followed.However, within the scope of the invention as claimed, modifications mayof course be made.

I claim :V

1. A sawing machine comprising an elongated supporting bar, a rack baronthe front end of said supportingl bar, a stationaryV jaw fixed to saidsupporting bar and projecting laterally therefrom at substantially rightangles thereto and in an opposite direction from the teeth of said rackbar, a substantially right angular movable jaw having a fulcrum at itsangle adapted to be adjustably engaged with said raclrbar,

one arm ofk said jaw projecting laterally from said supporting bar,parallel to and in co-operative relation with said stationary jaw togrip the trunk of a tree, the other arm of said movable jaw extendingrearwardly along said supporting bar to form an operating lever, asaw-carrying arm pivoted on one end of said supporting bar, asaw-carrying carriage slidably mounted on said arm, an operating handlepivotally connected with said carriage and adapted tobe folded along thesame when not in use, ,said

handle being formed in telescopically engaged sections, means on saidsupporting bar `adapted to hold said handle in its'foldedposition, meansfor holding said saw-carrying arm in line with said supporting bar toform a compact bundle when the saw is not in` from said stationary jawand having longitudinally spaced notches in its projecting edge, asecond `plate spaced above the first named pla-te and substantially aduplicate thereof, afrigid bar secured longitudinally upon said secondplate and having its rear end rigidly secured to the main supportingbar, the front ends of said rigid bar and the second plate being spacedabove the main supporting bar and free of connection therewith, amovable jaw removably received between said platesand having a fulcrumreceivable in the notches thereof, a rigid lever extending rearwardlyfrom said movable jaw, and a rack for holding said lever, said rackbeing secured to said main support-ing bar.

3. In a sawing machine, a main support' ing bar2 a saw-carrying armpivoted thereto at its rear end and having a guide, a curvedl trackprojecting laterally Jfrom said barand engaged by said guide, stationaryandmovable jaws projecting laterally from said main supporting bar inthe same direction as said track, the stationary jaw being disposed astationary jaw and track whereby they serve 10 to brace each other.

In testimony whereof I have hereunto affixed my signature.
